示例1: blender_camera_focal_distance
static float blender_camera_focal_distance(BL::RenderEngine b_engine, BL::Object b_ob, BL::Camera b_camera)
{
BL::Object b_dof_object = b_camera.dof_object();
if(!b_dof_object)
return b_camera.dof_distance();
/* for dof object, return distance along camera Z direction */

b_engine.camera_model_matrix(b_ob, b_ob_matrix);
Transform obmat = get_transform(b_ob_matrix);
Transform dofmat = get_transform(b_dof_object.matrix_world());
Transform mat = transform_inverse(obmat) * dofmat;
return fabsf(transform_get_column(&mat, 3).z);
